Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.






2. The joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans.






3. Large process of the fibular tarsal bone that projects upward and backward; commonly referred to as the point of the hock. Site of attachment of the gastrocnemius (calf) muscle and equivalent to the human heel.






4. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






5. Another term for the diaphysis of a long bone.






6. The joint between the pelvis and the sacrum that joins the pelvic limb to the axial skeleton.






7. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






8. An alternate name for joint cavity.






9. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.






10. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






11. Another name for cancellous bone.






12. Skull bones; external bones of the cranium. These bones make up the 'forehead' region of the skull and contain the large frontal sinuses. The cornual process in horned animals is an extenion of this bone.






13. Short - faced; breeds including Boston terriers - pugs - English bulldogs - and Pekingese.






14. A thin bone located beside the tibia in the lower leg region of the pelvic limb. It is a complete bone in the dog and cat - but only the proximal and distal ends are present in horses and cattle. It doesn't support any appreciable weight - but acts a






15. Long - faced. Example: Collie.






16. A general name for a lump - bump - or other projection on a bone; can be articular processes or nonarticular processes - which are usually sites where tendons attach.






17. The large hole in the occipital bone through which the spinal cord exits the skull.






18. A joint motion whereby the distal end of an extremity moves in a circle.






19. The distal sesamoid bone of the horse; located deep in the hoof behind the joint between the middle and distal phalanges.






20. The soft material that fills the spaces inside the bones; two types of bone marrow are red bone marrow - which forms blood cells - and yellow bone marrow - which consists primarily of adipose tissue.






21. The thin layer of hyaline cartilage that covers the articular surfaces of long bones in synovial joints; it forms a smooth layer over the joint surfaces of the bones - which decreases friction and allows free joint movement.






22. The bones of the skull that surround the brain. External bones: the occipital bone - the interparietal bones - the parietal bones - the temporal bones - and the frontal bones. Internal bones: the sphenoid bone and the ethmoid bone.






23. The large paranasal sinus in the frontal bone of the skull.






24. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






25. The microscopic - laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone - these consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacunae are present at the junctions






26. The outer layer of a bone that is composed of compact bone.






27. The paranasal sinus in the sphenoid bone; only present in horses.






28. Process on the cranial end of the second cervical vertebra (axis) that fits into the caudal end of the first cervical vertebra (atlas).






29. A lateral - projecting process of a vertebra.






30. The process of a vertebra that forms a synovial joint with an adjacent vertebra.






31. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






32. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






33. An immovable fibrous joint - such as the suture that unites most of the skull bones.






34. The hematopoietic type of bone marrow.






35. Bones of the forelimb that lie between the carpals and phalanges of quadrupeds.






36. The visceral bone in the heart of cattle that helps support the valves of the heart.






37. Skull bones that are part of the internal bones of the face; support part of the lateral walls of the pharynx.






38. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






39. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






40. The hinge joint on each side of the lower jaw that connects it with the rest of the skull.






41. The cartilaginous disk located between the bodies of adjacent vertebrae; acts as a shock absorber for the vertebrae.






42. Skull bones that are part of the external bones of the cranium; located on the dorsal midline just rostral to the occipital bone.






43. The end of a long bone; each long bone has a proximal and distal _____.






44. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






45. The hind limb.






46. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






47. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






48. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






49. The collective name for 37-38 bones of the head; it houses the brain and all the special sense organs.






50. A freely moveable joint; also known as a diarthrosis.
